Strictly Come Dancing star Seann Walsh has been publicly dumped by girlfriend Rebecca Humphries after being photographed kissing his married dance partner Katya Jones at the weekend.

Seann and Katya have both publicly apologised after photographs of the two sharing a kiss in the street were published in The Sun newspaper on Sunday, with the comedian putting it down to a one-off mistake.

'This is no excuse but it was a one-off drunken mistake which I am truly sorry for,' Virtually Famous star Seann acknowledged on Twitter.

In light of the story in today's newspaper I would like to offer my sincere apologies for my actions. This is no excuse but it was a one-off drunken mistake which I am truly sorry for.

Katya, who is married to fellow Strictly pro Neil Jones, also apologised on Twitter: 'I'm so sorry about any offence or hurt I may have caused with my actions.

'I wasn't thinking and it was a one-off mistake after some drinks. I love my husband and we are very happy together, this is not a reflection on our relationship.'

I’m so sorry about any offence or hurt I may have caused with my actions. I wasn’t thinking and it was a one-off mistake after some drinks. I love my husband and we are very happy together, this is not a reflection on our relationship.

Walsh's own girlfriend, Cockroaches and Morgana Robinson's the Agency star Rebecca Humphries, made her feelings perfectly clear in an open letter posted on social media late on Monday night.

In it, she publicly broke up with Walsh — telling him 'sorry I took the cat' — and stressed that she was 'not a victim' while accusing the comedian of reacting aggressively when she confronted him over his recent behaviour.

'It's incredibly good of Sean(n) and Katya to apologise in the media,' she wrote. 'I have received nothing other than the support of my family, friends and a host of strangers on the internet who all wanted to make sure I was OK.'

She went on: 'Those pictures were taken on October 3rd. It was my birthday. I was alone at home when Sean texted at 10pm saying the two of them were going for one innocent drink.

'We spoke and I told him, not for the first time, that his actions over the past three weeks had led me to believe something inappropriate was going on.

'He aggressively, and repeatedly, called me a psycho / nuts / mental. As he has done countless times throughout our relationship when I've questioned his inappropriate, hurtful behaviour.'

The actress concluded: 'But – this whole business has served to remind me that I am a strong, capable person who is now free; and no victim.

'I have a voice and will use it by saying this to any woman out there who deep down feels worthless and trapped with a man they love: Believe in yourself and your instincts.

'It's more than lying. It's controlling. Tell some very close friends, who if they're anything like my wonderful network, will swoop in and take care of the logistics and of you.

'It's important also to recognise that in these situations those who hold power over you are insecure and fragile, and their need for control comes from a place of vulnerability.

'I think it certainly does in Sean's case. Despite everything, I hope he gets what he wants from this. I'm not sorry I took the cat though.'

Digital Spy has reached out to Walsh's representative and the BBC for comment. Strictly Come Dancing chose not to address the controversy at all on spin-off show It Takes Too on Monday, but had earlier said Walsh and Jones would continue in the competition.
